Features of hardware and technological process formation in obtaining the compacted carbon materials

The paper demonstrates relevance of the research aimed at developing the advanced sorption materials based on the highly porous carbon material. It considers main stages of the sorption materials production including alkaline activation at the temperature of 400...750°C, post-processing and the resulting material compaction with research and determination of the most rational technological modes in its implementation. The study resulted in obtaining the activated and compacted carbon materials. The first material had specific surface area and porosity, respectively, of more than 2700 m2/g and 1.3 cm3/g, the second – of more than 2000 m2/g and 0.84 cm3/g. Sorption capacity of the activated and compacted carbon materials in regard to the organic dye (methylene blue) exceeded 2000 and 1700 mg/g, respectively, which showed the material ability to be a highly effective sorbent of the organic pollutants of the aqueous solutions. Based on the study results, schematic diagram of the hardware and technological process formation in obtaining the compacted highly porous carbon material is proposed, features of its implementation are presented.
